Safe Withdrawal Rate for Canadians: TFSA, RRSP, and OAS Optimisation

The most famous SWR is 4%, from the Trinity Study. While originally US-focused, Canadian research supports similar findings — a 4% withdrawal rate from a diversified global portfolio survives the vast majority of 30-year historical periods.

Your retirement duration is the most important factor. Someone retiring at 40 needing 50+ years may need a more conservative 3-3.5% rate. Someone retiring at 60 with CPP starting at 65 and OAS at 65-70 has a shorter pure-withdrawal period and can potentially withdraw more aggressively in the early years.

Withdrawal order matters enormously for Canadians. TFSA withdrawals are tax-free and do not count as income (no OAS clawback). RRSP/RRIF withdrawals are fully taxable income. A common strategy: draw from non-registered accounts and TFSAs first, delay RRSP/RRIF withdrawals to benefit from continued tax-deferred growth, and begin mandatory RRIF minimums at 72.

CPP and OAS effectively reduce your required SWR from portfolio assets. If government pensions cover $23,000/year of a $50,000/year budget, your portfolio only needs to produce $27,000/year — a much lower effective withdrawal rate on a $1,000,000 portfolio (2.7% vs 5%).

Dynamic strategies — reducing withdrawals by 10-20% during bear markets — dramatically improve portfolio longevity. Combined with the CPP/OAS floor, Canadian retirees have a structural safety net that makes the 4% rule more conservative than it needs to be for many.
